Description

Technical Field

[0001] This utility model relates to the field of adhesive application equipment technology, specifically to an adhesive application equipment for controlling the U-shaped gaps in battery cells. Background Technology

[0002] Prismatic cells are lithium-ion battery units encapsulated in a square metal casing (such as aluminum or stainless steel), and are widely used in electric vehicles, energy storage systems, and other fields. Due to their balanced safety, cost, and assembly efficiency, prismatic cells remain the mainstream choice for power batteries, and their performance will continue to be optimized through material and structural innovations in the future.

[0003] The application of the U-shaped adhesive to the square-shell battery cell is a key process step in battery manufacturing. It is mainly used to fix the internal electrode assembly (wound core or stacked assembly) and prevent deformation caused by electrode displacement, short circuit or expansion. The functions of the U-shaped adhesive include: (1) structural fixation: preventing displacement or deformation of the internal electrode (positive and negative electrodes) and separator during charging and discharging due to expansion / contraction; (2) insulation protection: avoiding short circuit caused by contact between the tabs or electrode edges and the metal shell; (3) stress buffering: relieving the impact of battery cell expansion on the mold.

[0004] In existing technologies, the adhesive application process for prismatic battery cells, involving two applications on each of the long and short sides, is completed in two separate workstations. The bonding position between the long and short sides, as well as the required gap at the bottom, both require visual guidance for control. However, visual guidance carries the risk of overlap and cannot guarantee the stability of the zero-gap position.
